What Will I Learn?

• Stars are the workhorses of the universe and account for most of its mass. They come in many shapes and sizes, some as small as just a few miles across and others that are as large as much of our solar system. Some are hundreds of times hotter than the Sun and others are just a few thousand degrees. When stars start running out of fuel they do some crazy things like explode into supernovae or implode into tightly packed white dwarfs or black holes.
